I have a large cyst just at the top of my shoulder blade. I noticed it about 4 years ago, it was the size of a golf ball now the size of a large egg. I did see a surgeon 2 years back, he said it was just a fatty tissue and not to worry about it. He did not want to operate to remove it as where it was located it was hard to keep the stitched closed and hard to keep it from not being infected thereafter. But the past few weeks and now the past few days it is becoming painful just below the lump and feels like, when I move, turn my head, sit up or down, I feel a pulling and pain like a knife is being stuck in me. The pain is making me nauseous. Your thoughts ?
